Improvement in yarn-spooling machinery



UNITED. STATES JOSEPH B. BANOROFT, or HOPEDALE, MASSACHUSETTS.

PATENT OFFIo IMPROVEMENT IN VARN- SPOOLING MACHINERY.

Specification forming part of Letters Patent No. I 80,106, dated July 25, 1876; application filed February 21, 1876.

To all whom it-mag concern:

Be it known that I, J OSEPH B. BANOROFT, of Hopedale, of the county of Worcester and State of Massachusetts, have invented a new and useful improvement in Machinery for Spooling Yarn; and'do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawing, of which Figure l is a front elevation, and Fig. 2 a vertical section, of a spoofing-machine spindle, its bolster, andbobbin-rest, provided with my invention. Fig. 3 is a vertical section of such a spindle, bolster, and bobbin-rest as heretofore in general use.

By inspection of the latter figure it will be observed that there is between the bolster B and the bobbin-rest R a portion, a, of the spindle S which is uncovered,'aml also that there is no cover to the bolster or its spindlesupporting bearing. Under such circumstances waste is apt to accumulate on and become wound upon the exposedpart a, and work down into the bolster, and thereby impede the operations of the spindle. To avoid or prevent such is one object of my improvement.

In carryingtout my said invention I combine with the spoofing-machine spindle A, its

bolster B, and a bobbin-rest, G, separate from the whirl, a'sleeve, D, to encompass the spindle and extend down from the said rest to the bolster; or I construct the bolster with a cylindrical extension, (1, to project above the oil-troughb, and I provide the bobbin-rest G with a c vlindrieal sleeve, D,to extend down from it, to and around the extension a, in manner as represented in the drawings.

By such means all that part of the spindle which is between the bolster and the bobbinrest,'as well as the spindle-hearing or bore of the bolster, will be covered, and thereby be protected from waste, the sleeve revolving with the spindle and the bobbin rest, while they may be in operation.' Furthermore, the spindle is .provided,just above its whirl E, with a cylindrical cup, F, that encompasses it, and extends upward within an annular or circular space, Gr, made within the bolster, and upward from its foot, from which it will be seen that the bolster not only extends down within the oil-cup, but also down around it.

The bore of the bolster is, or may be,

grooved helically from top to bottom, and thereis from the oil-trough into the bore of the bolster a passage or' duct, 0, to convey oil from the trough into the bearing.

The cup F and the annular space G serve to prevent loss of oil from the bolster, and

they alsoprevent waste or filaments from the bore or bearingpt' the bolster is protected from dust and fibrous waste, and so is that part of the spindle which is between the bolster and the bobbin-rest.

I am aware that the bolster ot' a ring or'a throstle-spindle has been extended down into a cup fixed to the spindle, and also that while so extended the bolster has been made to encompass the cup. Therefore, I do not claim such irrespective of a sleeve extended down from a bobbin-rest to oraround abolster, and the part of the spindle between the said bolster and rest.

When the sleeve is so useditindireetly protects the cup from waste or dust that otherwise might work down through the bolster and into the cup.

I claim as my invention as follows-that is to say:

1. The bobbin-supporter 0 separate from the whirl E, and arranged with it on the live-spindle A, and provided with the sleeve D, all as set forth, in combination with the bolster 13, arranged between the said whirl and, bobbinsupporter, and furnished with the oil-trough b, and with the neck a extended above the said oil-trough b, and within the sleeve D,

all being substantially as shown and described.

2. The spoofing-machine, live-spindle A,

trough b, and arranged between the said whirl and bobbin-supporter, and extended up within thelatter, and provided with an an;

nular chamber, G, to receive the cup F, all

being essentially as shown and described. Witnesses: JOSEPH B. BANOROFT.
